Hi this is Ahmad from Iraq and I’m here
to explain what does frame rate really mean? To explain this simply, imagine that you have
a note book and you draw a ball that moves down on each paper on the same location but
it moves lower on each paper, in a way that if you flip the pages quickly, it looks like
as if the ball is moving. Now the same thing happens in a digital video
the same basic idea, BUT instead of papers, there are frames. Each paper represents a
digital frame. Now the camera doesn’t record motion, it
records what is called frames at different rates for example 30 FPS 24 FPS… etc, the
FPS stands for Frames Per Second. If your camera is recording 30 frames per second, that
means that every second it is recording 30 frames that are then combined and compressed
to make a video. There are cameras out there that can record
thousands of frames per second that are used mostly in slow motion videos by extending
the frame rate from for example a 1000 FPS, down to 30 FPS which keeps the smoothness
of the video at 30 FPS, but much slower because it has been extended.
Each frame has a resolution. The bigger the size of the frame, the bigger the resolution
and thus a larger video which translates to a more detailed image.
I’m not gonna go through the different resolutions of a video, because technology is advancing.
So we have a full HD 1080p videos, 2k videos, 4k videos, and even 8k videos. Those are
sometimes called ultra HD videos. Which they have a resolution that is larger than 1920x1080p,
or double that resolution. Which is the standard full HD video.
What does the P in 1080p means you might ask? It stands for progressive, which is the way
that frames are displayed. There are two types, ‘Interlaced’ and ‘progressive’ but
progressive is the most common in videos. In video games and graphically intense 3D
applications how much frames are processed per second, depends on the strength of your
computer/device, and the GPU processing power, and how much graphically intense the game
is. We are advancing more and more these days, that
even phones can capture high resolution videos and images.
Back when films used to be made in tapes they also used to use the same basic idea
images that are moving to give the illusion of motion. Please click the like button if you enjoyed
